dc.descriptionTuberculosis-associated immune reconstitution inflammatory syndrome (TB-IRIS) is a substantial problem in HIV/TB coinfected patients commencing antiretroviral therapy (ART). The immunopathogenesis of TB-IRIS includes increased production of proinflammatory chemokines and cytokines, including interleukin-18, which is a signature cytokine of the nucleotide-binding domain and leucine-rich repeat pyrin containing protein-3 inflammasome. We compared plasma levels of interleukin-18 and other biomarkers of monocyte/macrophage activation in the prediction and characterization of TB-IRIS. Methods: Biomarkers were assayed pre-ART and during TB-IRIS, or equivalent timepoint, in a case–control study of Malaysian HIV patients with paradoxical or unmasking TB-IRIS (n¼15), TB no IRIS (n¼14), and no TB or IRIS (n¼15). Findings for interleukin- 18 were verified in another cohort of patients with paradoxical TB-IRIS (n¼26) and their controls (n¼22) from India. Results: Interleukin-18 was higher in TB-IRIS patients pre-ART and during the event in both Malaysian patients (P<0.0001) and Indian patients (P<0.01). CXCL10 was higher pre-ART (P<0.001), mainly in paradoxical TB-IRIS patients, and during TB-IRIS (P<0.001), whereas CXCL8 was only higher during TB-IRIS (P<0.001). Soluble(s) CD14 was increased in all patients with HIV/TB coinfection pre-ART and during TB-IRIS or equivalent time-point, compared with patients without TB. In contrast, interferon-g was lower before and during TB-IRIS. By receiver operating curve analysis, CXCL10, and/or interleukin-18 pre-ART were predictive of TB-IRIS. Conclusion: Plasma interleukin-18 levels pre-ART are candidate biomarkers for predicting paradoxical and unmasking TB-IRIS and should be investigated for risk stratification and elucidation of disease pathogenesis.
